Im looking for instructions on how to set up Nextcloud
remotely from the Internet on my “Umbrel Home” server. I own a domain. I have already had some experience with the facility. I already have a Nextcloud (NextcloudPi) running on the Raspberry Pi. There I was able to configure the domain etc. because there is a wizard with a GUI there. Unfortunately, this menu item is not available in Nextcloud on the Umbrel. Presumably the configurations have to be done via command line.
Tailscale ist not an option for me.
I would be happy if you could help me.
